I was referred to Shawn at Courthouse Automotive by a friend when my Cadillac SUV began giving me electrical problems. Having just moved to Virginia from California I really didn’t know where to go. I am so happy to have met the people at Courthouse Auto! They are courteous, smart and I was instantly at ease with using them to fix our family car.

We recommend you get a seven point preventative cooling system maintenance check performed at least once every two years. Consult your vehicle owner’s manual for specific guidelines. The cooling system inspection identifies areas that need attention, and consists of the following:

A visual inspection of all cooling system components, including belts and hoses

A radiator cap pressure test to check the recommended system pressure level

A thermostat check for proper opening and closing

A pressure test to identify external leaks to the cooling system parts including the radiator, water pump, engine coolant passages, radiator, heater hoses and heater core

An internal leak test to check for combustion gas leakage into the cooling system

Cooling System Operation

The Cooling System carries heat away from the engine and maintains the operating temperature by circulating anti-freeze/coolant through the engine, and carrying it to the radiator for cooling.

Modern automobiles operate in a wide temperature range, from well below freezing to over 100 F. The fluid used to cool the engine must have a low freezing point, high boiling point, and the ability to transfer heat. An adequate amount of antifreeze/coolant and water reduces the possibility of engine over-heating and freezing, as well as contains additives to prevent rust and corrosion in the cooling system.

Water holds heat well; however, water alone freezes at a temperature too high to be used in engines. The fluid in most vehicles mixes water and antifreeze or coolant. With this mixture, the boiling and freezing points improve significantly.

Coolant temperatures sometimes reach 250 to 275 degrees Fahrenheit. Even with antifreeze added, these temperatures boil the coolant. To prevent boiling, the cooling system raises the coolant boiling point by pressurizing it. Most systems pressurize coolant at 14 to 15 pounds per square inch (psi) which raises the boiling point approximately 45 degrees Fahrenheit.

Our skilled technicians know the importance of a properly working cooling system. Come in to our shop or call or email us today for a thorough inspection.
